Hybrid automata. We summarize several recent results about hybrid automata. Hybrid automata are studied here from a dynamical systems perspective. Hybrid automata can be viewed as a generalization of timed automata in which the behavior of variables is governed in each state by a set of differential equations.

Hybrid automata provide a language for modeling and analyzing digital and analogue computations in real time systems. From verification to implementation. For more information please contact christian schilling.

We show that many of the examples considered in the workshop can be defined by hybrid automata. Our goal is to demonstrate that concepts from the theory of discrete concurrent systems can give insights into partly continuous systems and that methods for the verification of finite state systems can be used to analyze certain systems with uncountable state spaces. The code and models used in the evaluation can be found here.

A hybrid system is a dynamical system that exhibits both continuous and discrete dynamic behavior a system that can both flow described by a differential equation and jump described by a state machine or automaton often the term hybrid dynamical system is used to distinguish over hybrid systems such as those that combine neural nets and fuzzy logic or electrical and mechanical. Necessary and sufficient conditions for existence and uniqueness of solutions are derived and a class of hybrid automata whose solutions depend continuously on the initial state is characterized. In automata theory a hybrid automaton plural.
